compressor is reoperated. The same phenomenon
occurs when a power is on. As a phenomenon that
the compressor is reoperated after a delay of 3
minutes, the indoor fan is adjusted automatically
with reference to a temperature of the air blew.
The speed of the indoor fan is set to LL in DRY mode.
Fan speed is selected automatically in AUTO mode.
Compressor operation is controlled automatically in
DRY mode depending on the room temperature and
humidity.
Timer is being activated and the unit is in ready
mode. The unit operates normally if the timer
operation is cancelled.
The compressor stops intermittently or the fan
speed of the indoor unit decreases to prevent inside/
outside air frozen depending on the inside/outside
air temperature.
When the unit is turned off while de-ice is activated,
the compressor continus operation for up to 9
minutes(maximum) until the deice is completed.
The compressor and indoor fan stop intermittently if
room temperature exceeds a setting temperature in
order to protect the compressor from overheated air
in a HEAT mode.
The compressor operates in a reverse cycle to
remove exterior ice in a HEAT mode, and indoor fan
and outdoor fan do not operate intermittently for
within 20% of the total heater operation.
